I wouldn't want to generalize this, but it is not infrequent that people
mistakenly iterate over strings when they want to treat them atomically.
difflib not withstanding, and keeping Guido's pronouncement in mind, I
do think people want to treat strings atomically much more often then
they want to treat them as a sequence of characters.
